Study to Compare Standard Perimetry With the New Scotoma-Oriented Perimetry (SCOPE) Using a New Fast German Adaptive Threshold Estimation (GATE) in Glaucoma Patients

Pilot Study to Compare the Humphrey Field Analyzer (HFA) 30-2 Swedish Interactive Threshold Algorithm (SITA) Standard Perimetry With the New Scotoma-Oriented Perimetry (SCOPE), Using a New Fast GATE (German Adaptive Threshold Estimation) in Glaucoma Patients Under Topic Therapy

The purpose of this study is to compare the two psychophysical perimetric techniques regarding progression of the visual field.

Inclusion Criteria:

• primary open angle glaucoma (POAG)
• spherical ametropia max. ± 8 dpt
• cylindrical ametropia max. ± 3 dpt
• distant visual acuity > 10/20
• pupil diameter > 3 mm

Exclusion Criteria:

• diabetic retinopathy
• asthma
• history of epilepsy or significant psychiatric disease
• medications known to effect visual field sensitivity
• infections (e.g., keratitis, conjunctivitis, uveitis)
• severe dry eyes
• miotic drug
• squint
• nystagmus
• albinism
• any ocular pathology, in either eye, that may interfere with the ability to obtain visual fields
• keratoconus
• intraocular surgery (except for uncomplicated cataract surgery) performed < 3 month prior to screening
• history or signs of any visual pathway affection other than glaucoma
• history or presence of macular disease and/or macular edema, ocular trauma, medications known to affect visual field sensitivity
